Frank Nitty Posted November 20, 2017 Share Posted November 20, 2017 I took the plunge and purchased a 4K UHD TV to use as a secondary monitor. However, after I connected my HDMI cable, started my system, selected the 10.13.0 partition from the Clover boot menu, and waited for the Apple logo status bar to load, I get a "No signal" error. What gives? Anybody with prior knowledge of this issue and/or could give me some useful advice to move forward would be greatly appreciated.

PPCnostalgic Posted November 20, 2017 Share Posted November 20, 2017 Hello. Is the UHD 4K monitor the only screen connected? Did you check that HDMI output with another monitor? BTW you said your HS partition is the 10.13.0 You should update to the newer 10.13.1 build 17B48 Link to comment Share on other sites More sharing options...
wern apfel Posted November 20, 2017 Share Posted November 20, 2017 I use a UHD display via DP without any issue, from 10.9 to 10.13. Not all graphic cards are supporting 4k via HDMI. Some HDMI cables are not 4k compatible. The pixel-patch might help. Link to comment Share on other sites More sharing options...
Nubira Posted November 20, 2017 Share Posted November 20, 2017 Just to make sure did you pick the right input source on your TV settings? Link to comment Share on other sites More sharing options...
Denicio Posted November 20, 2017 Share Posted November 20, 2017 I use a Samsung 4k TV as my main monitor. It is connected through DP -> to HDMI 2.0 convertor from Club3D, works great and outputs 4k @ 60hz. 1 Link to comment Share on other sites More sharing options...
Frank Nitty Posted November 21, 2017 Author Share Posted November 21, 2017 Hello. Is the UHD 4K monitor the only screen connected? Did you check that HDMI output with another monitor? BTW you said your HS partition is the 10.13.0 You should update to the newer 10.13.1 build 17B48 Yes, and it's not a monitor but a TV. I have been having problems updating to 10.13.1. Each time I run the update and it goes through the required restart, 'About this Mac' shows 10.13 only as if nothing happened. I use a UHD display via DP without any issue, from 10.9 to 10.13. Not all graphic cards are supporting 4k via HDMI. Some HDMI cables are not 4k compatible. The pixel-patch might help. I'm referring to rig #1 in my sig which uses a GTX 1070. My UHD TV has no DP ports, only HDMI. I just bought a HDMI 2.0 cable so I'll try it out later and see if that does the trick. Just to make sure did you pick the right input source on your TV settings? Based on the OP keep in mind that if I didn't have it on the right input then how would I have seen the Clover booatloader menu and subsequent Apple logo with loading bar that follows. I use a Samsung 4k TV as my main monitor. It is connected through DP -> to HDMI 2.0 convertor from Club3D, works great and outputs 4k @ 60hz. That just might work for me. What version did you get? Just saw it online for $30. Link to comment Share on other sites More sharing options...
Frank Nitty Posted December 1, 2017 Author Share Posted December 1, 2017 UPDATE: So I purchased the following adapter from Monoprice here (half the price of the Club3D brand Denicio suggested) and the final result is: it works like a charm. Able see/run macOS 10.13.1 in 4K on my GTX 1070 and it looks amazing w/ all the screen real estate. 1 Link to comment Share on other sites More sharing options...
